For the purpose of illustrating my invention,

I have shown in Fig. 1 a portion of a window. I0 .20 having a frame II in which is slidably mounted a pair of double hung sash l2 and I3.

The frame H consists of vertical frame members M which have secured to them stops or runners I5, l6 and I1 between which tracks "25 I8 and I9 are formed and in which the sash l2 and I3 slide.

The sash I 2 includes stiles 2| and a meeting rail 22 together with such other parts as are customarily found in sash. The sash l3, simi- 30 larly includes stiles 23 and a meeting rail 24 which is adapted to engage the rail 22 to close the sash when the rails 22 and 24 are opposite one another. As will be noted inFig. 1, the corner 25 of the rail 24 has a certain amount of clear- 35 ance with reference to the stile 2| of sash l2 which is brought about by the use of the stop or runner l6. This clearance has been designated by the reference numeral 26 and is utilized with my invention as will be presently more fully 40 described.

My invention proper consists of a mounting 27 which is adapted to be attached to the stile 2| of 'sash I2 and which has detachably secured to it a stop 28 which is adapted to engage sash '45 I3 and to limit relative sliding movement of the sash. These parts will now be described in detail.

The mounting 21 is constructed from a blank of sheet metal which is U-shaped in form to pro- 50 vide two legs 32 and 33 and a connecting portion 34 therebetween. By means of this construction an opening 29 is formed in the center of the blank extending through one edge thereof. The marginal portion 3| of the blank extending about 255 the opening 29 is turned outwardly therefrom, as best seen in Fig. 4. This forms two tongues 35 and 36 which extend along the legs 32 and 33 and flanges 31 and 38 issuing therefrom. The flanges 31 and 38 lie in the plane of the blank from which the mounting is constructed and form a base for attaching the mounting to the stile 2|. In similar manner the marginal portion 3| may be turned up at the rear of the opening 29 to form an abutment 39 and. a flange 4| connected therewith. Both of the tongues 35, 36 and the abutment 39 lie in continuation and likewise the flanges 31, 38 and M lie in a single plane. The tongues 35 and 36 are arranged in converging relation so that the same form a dove-tailed slot therebetween. The flanges 31 and 38 are constructed with holes 42 through which suitable screws 43 (Fig. 1) may be inserted for attaching the mounting to the stile 2 I.

The stop 28 is preferably construct-ed of some resilient material such as rubber or any of the similar compositions now used in place thereof. This stop comprises a body M having spaced parallel lateral surfaces 58, a bearing surface 41 and an upper surface 40. The surface 49 con verges with respect to the bearing surface i! to form a wedge ll at the toe end of the body i l. At the heel end of this body the same is con structed with two grooves 5i which are parallel to one another and which toe inwardly to form a dove tail adapted to be inserted into the dovetailed groove formed by the tongues 35 and The tongues 35 and 3B are adapted to be received within the grooves 5i and the stop 28 may he slid longitudinally along the tongues 35 and it until movement of said stop is arrested by means of abutment 39. In the construction of. the mounting 2?, the height of the tongues 35, 35 and 39 is made less than the clearance Eli between the rail 2d of sash l3 and the stile ii of sash l2. This permits of the sliding of the sash 13 past the mounting 21 whereby the window may be operated in the customary manner when the stop 28 is removed.

In the installation of the device the mounting 27 is attached to the stile 2| of sash i2 by means of the screws l3 which extend through the holes 62 of the flanges 3'! and 39 and are screwed into the stile 2!. Mounting 2i so arranged that the abutment 39 is uppermost and so that the opening 25 opens downwardly. Due to the construc tion of the said mounting, after the same has been applied, the sash may be slid relative to one another without interference with the mounting 27. When it is desired to limit relative sliding movement of the sash, stop 28 is applied to the mounting Z'l by sliding the same along the tongues'fiS and 3G. The body i l of said stop is of a height at its heel end greater than the clearance 25 so that, when the windows are moved relative to one another, the corner '15 of rail 2d of sash 13 engages the converging surface 38 of the wedge 49 and wedges the sash tightly against the runners Hi and ii, thus limiting opening movement of the sash. Such movement tends to force the body' 4 along the tongues 35 and ill; and toward the abutment 39. This abutment prevents disengagement of the stop from the holder and prevents further movement of the sash.

It will be noted that the bearing surface 4'! of the body 4 1 of stop 28 bears directly against the surface of the stile 2i throughoutits entire extent. By means of this construction, rattling of the device is entirely prevented. Elhould the mounting 2'! become loose, the stop 28, being disposed directly between the two sash and without any intervening structure, wou d positively engage both parts and prevent relative movement therebetween. Any pressure applied to the surface 48 of the body Mi of stop 28 tends to spread out the material of the said stop and particularly at the grooves 5i which causes outward movement of the mounting 21, thereby urging the same away from the surface of thc stile 2i and thus taking up the play which might have resulted in this mounting becoming loose. In this manner rattling is prevented, even though the mounting 21 may become loose.

In Fig. 2 I have shown my invention used as a door stop. In this figure a door frame 6| is shown and to which is hingedly connected a door (32 by means of hinges 53. The floor of the room, in which the door and frame is installed, is indicated by the reference numeral 64. In using my invention in conjunction with the door 62, the mounting 21 is attached to the floor and the stop 26 is secured to the mounting in a manner such as to engage the lower corner of the door 62 when the same is swung up to the desired ultimate position. On removal of the stop 28 the door may swing free of the mounting Z7 and thus function in its ordinary manner.

My invention is highly advantageous in that an extremely simple and practical construction is provided, whereby the opening of windows may be limited. .Vith my invention the stop can readily be removed and when once removed the window operates entirely in the same manner as without the fastener. My invention can be c0hctructed at a nominal cost and is easy to install. My device is so simple that the operator can readily understand the method of use and no experience or intricate instructions are needed to explain the method of operation. Should the stop fall out of. the mounting the same would not prevent operation cl the sash. My invention will not mar or injure the closure with which it is to be used. The window utilizing my improved closure fastener becomes entirely rattle proof when the window is opened and even if the mounting becomes loose, rattling is still prevented.

Changes in the specific form of my invention, as herein disclosed, may be made within the scope of what is claimed without departing from the spirit of my invention.
